Influence of Human Activities on the Mire in Zoige Plateau and Countermeasure

Abstract

The change of Zoige Plateau mire as the result of the human activities is discussed in this paper,by way of the comparative analysis the mire vegetation,mire soil (infusible N,P,K in Chuolajiang lakeshore (CLJL) mire soil without disturbance plot is higher than its in ninth road group (1) which is low degree disturbed or its in ninth road group (2) which is high degree disturbed.But the solubility N,P,K(namely quick result N,P,K) is in the adverse,its conttent in the disturb mire pasture soil is higher than its in the original mire.Tht analysis of mire hydro chemistry,mire microclimate shows made known that the region environment have distinctly changed in the recent years,resnlting in the pasture degeneration,wild animal decrease,mouse harm increase,part of the land is sandy and salt.This paper analyzed the cause of the above problem and puts forward some preventing countermeasures.
